BEHIND THE BUILD: The base is a 1944 BSA M20.
The bike name is “GRÅBEIN” directly translated from norwegian to english “Grey Legs”, an old norwegian slang word for “wolf” which, in Norway, is considered a taboo word to mention (you call for the wolf if you use it).
Frame and fork are from a 1944 M20, the engine from a 1950`s B33 500cc, the gearbox is the original M20 with Triumph clutch, 23″ front wheel from an Honda XL 250 with Mitas speedway tire, 18” rear wheel from a Yamaha YZ 250 with Heidenau K60. The gas tank comes from 1975 Yamaha DT 250 customized to fit over the engine. All parts used are old parts customized or hand made.
